Followed the instructions of the related tutorial (https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-on-ubuntu-20-04-with-a-lamp-stack) to the letter, ended up WordPress not being able to establish a connection to the database. WordPress and database are on the same server (Ubuntu 20.04 with LAMP stack). I can login to mysql using the WordPress user and password, even when specifying -h localhost to mysql. DB info is properly given in wp-admin.php. WordPress resides in /var/www/wordpress, with a subdomain pointing at that folder on my server.
